Am I the only one that thought Superman was a colossal deuche? He singlehandedly killed off the only people who had the chance of repopulating his species, and then (if I remember correctly) had the balls to bitch about being all alone. Now I do realize that the other Kryptonians were dickweeds as well, but they at least recognized that there were potentially other planets they could colonize.

i mean, they could just get used to the earth and become freaking gods. THEN commit the genocide because no weapon on earth can hurt them and hopeman will become despair man because there is only one of him and a small army of them.

Did you miss the entire Kryptonian backstory? The Kryptonians needed to die. If they had repopulated under Zod, they eventually would've been able to go to other planets and cause massive genocide there as well. Better that the 15 or so of them die than trillions of other innocent lives.

The other Kryptonians wanted to rewrite the earth's atmosphere and repopulate. While Hopeman didn't want to see his people go, you could tell he was desperate, he also wanted to prevent the genocide of an entire species. In his opinion, and rightly so, Krypton had it's time and screwed the pooch. He wasn't going to allow genocide, even if it force him to be alone.
